CP5 Nonimaging Nuclear Medicine Probe - Musculoskeletal System ICD-10-PCS
The CP5 code range contains 5 ICD-10-PCS codes for Nonimaging Nuclear Medicine Probe procedures on the musculoskeletal system. 4 of the codes are billable and valid for inpatient claim submission in fiscal year 2026.
Root Operation Definition
Nonimaging Nuclear Medicine Probe: Introduction of radioactive materials into the body for the study of distribution and fate of certain substances by the detection of radioactive emissions; or, alternatively, measurement of absorption of radioactive emissions from an external source.

About the CP5 Code Range
The ICD-10-PCS root operation CP5 - Nonimaging Nuclear Medicine Probe involves using a nuclear medicine technique to probe a body system without producing an image. This operation is specifically applied within the Nuclear Medicine section and targets the Musculoskeletal System.
This procedure uses radioactive substances to detect physiological or metabolic activity in musculoskeletal structures. The included codes specify different anatomical locations, such as the Spine (CP55ZZZ), Upper Extremities (CP5NZZZ), and Lower Extremities (CP5PZZZ). Additionally, CP5YYZZ denotes probing the musculoskeletal system using other radionuclides not specified in other codes. Unlike imaging nuclear medicine procedures, this nonimaging probe evaluates functional information by measuring radioactivity without generating diagnostic images. Accurately coding these nonimaging nuclear medicine probe procedures ensures precise documentation of nuclear medicine diagnostic assessments within musculoskeletal care.
Questions About This Page
How many billable codes are in the CP5 range?
Of the 5 codes in this range, 4 are billable and valid for inpatient claim submission from October 1, 2025 through September 30, 2026. Table header codes group them but cannot be reported on claims.
What does the CP5 range classify?
The range classifies Nonimaging Nuclear Medicine Probe procedures, introduction of radioactive materials into the body for the study of distribution and fate of certain substances by the detection of radioactive emissions; or, alternatively, measurement of absorption of radioactive emissions from an external source, performed on the musculoskeletal system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
